The 24th Amendment to the United States Constitution, ratified on January 23, 1964, prohibited the use of poll taxes in federal elections. Poll taxes were fees that voters had to pay in order to cast their ballots, which disenfranchised many African Americans and other marginalized communities who could not afford to pay. The 24th Amendment was a significant victory for the civil rights movement and played a key role in ensuring greater access to the voting booth for African Americans and other minority groups. This amendment helped to dismantle one of the barriers that had been used to suppress the political power and voice of Black Americans, leading to greater participation in the democratic process.
